Climate change is reflected in Finland’s temperatures, too. Since the 1960s, the annual mean temperature in Finland has risen on average by 0.3 degrees per decade. Owing to human activity, the global climate is constantly becoming warmer, but the intensity and impacts of the change vary from region to region. In Finland and other northern regions, temperatures rise more rapidly than the global average. The rate of warming in the Arctic regions is about double the global average. In Finnish Lapland and northern parts of Fennoscandia, the 1930s were exceptionally warm; in those areas, temperatures are therefore just passing the old records.
In Finland, winter temperatures are rising on average more than summer temperatures. For instance in Helsinki, the year 2008 broke all previous temperature records. However, the record-high mean temperature is explained by the exceptionally warm and mild winter. Especially in southern and central parts of the country, mild winters will be more frequent. Since there will be less snow, winters will also be darker. Summers will become warmer, too, but this effect will be seen and felt more slowly than the warming of winters.
The impact of climate change on temperatures is still small when compared against the wide natural variation, but in the coming decades the change will gradually become clearer. However, even though the climate changes, its variability will remain. In other words, some periods will still be colder and some others warmer than average.
